Tilt Detection application
This tilt demo enables you to evaluate the tilt application using both accelerometers' data. It showcases the
tilt detection on the X and Y axes. The tilt angle degree is the addition of the coarse and the fine readings:
•
The coarse reading is the integer angle.
•
The fine reading is the fractional angle (also known as arcminutes).
4.3.1
Active screen
The Active screen enables you to evaluate the built-in algorithm for detecting the device’s tilt, in
conjunction with the device’s resolution mode (coarse or fine). You can evaluate the default configuration
and modify the settings to tailor the demonstration to your target application.
Note:
Before changing any of the Active screen’s
settings, select the Standby option button.
Note:
In order for the tilt to
be registered, the
device must be held
up so that it is facing
you (or held on a
desk on its edge).
